  title: FHIR Single API - US Core 6.1.0 Encounter API
  description: 'Fast Healthcare Interoperability Resources (HL7® FHIR®, pronounced "Fire") defines a set of "Resources" that represent granular clinical concepts. The resources can be managed in isolation, or aggregated into complex documents. Technically, FHIR is designed for the web; the resources are based on simple JSON structures, with an http-based RESTful protocol where each resource has predictable URL. Where possible, open internet standards are used for data representation. This OpenAPI specification is aligned to the HL7 FHIR US Core Implementation Guide STU 6.1.0 on FHIR R4 (v4.0.1).
